I did a search and came up with two numbers

143-4003

143-4303

Both are listed for a GM V-6 at Summit

Which ones are the ones to use on my 91?

thanks

Ron
 
You need the 2.8 V6 Chevy studs,

233-4003 are 6 point nuts

233-4303 are 12 point nuts

The 6 point version is almost $30 cheaper, about $85.
 
Don't forget to order some ARP Assembly Lube, and ARP Teflon Thread Sealer also as they are not included with the stud kit.
